Stray Light Optical Technologies
The Leader in Plasma Lighting Fixtures
Stray Light has just launched a new website. In fact you’re looking at it right now!
Our goal is to establish a web presence that’s as high-tech and efficient as our company, and we welcome your feedback on how we’re doing. Take a look around, kick the tires and let us know if the site tells you everything you want to know about Stray Light.
Comparing Light Emitting Plasma™ (or any other high-output commercial light source) to Induction will lead right away to Induction’s strong point: its lifetime. Under controlled conditions induction will outlast most commercial lighting technologies. The limiting factor is that induction technologies still have a reputation for failing to illuminate in cold weather, leaving these as an impractical solution in much of the U.S., European, and Asian outdoor lighting markets. Directionality of induction light sources is also very poor leading to fixture inefficiencies despite tolerable source efficiencies. Low lumen density results in fixtures the size of indoor fluorescent office “trougher” lights intend to replace 400W MH, which often eliminates these fixtures simply due to poor aesthetics and high wind loading factors. Plasma and Induction CRI and color temperatures are comparable for 01 fills, however Plasma 02 fills are still superior.

Light Emitting Plasma™ and Light Emitting Diode (LED) provide similar reliability and lifetime. Directionality of LED light is good. Properly balanced high-end LED fixtures are beginning to achieve satisfactory CRI and color temperatures, although this comes at a significant premium. Lumen density of LED’s is still low compared with Plasma. It still takes about 100 typical high lumen LEDs to produce similar lumen output to 1 Plasma source. This high component count combined with high thermal sensitivity which requires large heat sinks yields fixtures which are typically larger, heavier, and more expensive than a Plasma fixture for the same lumen output. LED does have the advantage of instantaneous turn on. LED is a good fit for lower lumen applications such residential indoor and accent lighting, but not high lumen applications.
